What is the Value of 3x - 4 if 2x plus 1 equals -5?
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
What value for X makes the equation 3x plus 3 equals 2x plus 6 true?
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
What is answer to 5x-4 equals 3x plus 6 equals?
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
Find the coordinates of the x-intercept 2x plus y equals -6?
-4
If 2x - 6 equals 4 then what is the value of x?
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
What is the value of x if 2x-6 equals 4?
5
If x equals 3 and y equals 4 what is the value of 2x plus y - 1?
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
What is 2X plus 4 equals 10?
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
How do you solve 2x-y equals 4 and 2y equals 4x-6 using the substitution method?
2x-y = 4 and 2y = 4x-6 pick either equation and solve for one of the variables the first equation: y = -4 + 2x plug in the value of variable you solved for into the other equation 2(-4 + 2x) = 4x -6 then solve -8 + 2x = 4x-6 -2 = 2x x= -1 then plug in the value you have found into either original equation to find the value of the other variable 2(-1) - y = 4 -2 - y = 4 -y = 6 y = -6
What is the value of 2x when x equals 3?
6
If x equals A squared what is 2x-4?
6
What is the value of x in 6 plus 2x equals x-6?
6 + 2x = x - 6 2x - x = -6 -6 x = -12
What is the Value of 3x - 4 if 2x plus 1 equals -5?
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
Solve the equation 2x - 4 equals -10?
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
What is the answer to 4-2x equals 10?
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
What is the value for x in the following linear system of equations 2X plus 3Y equals 6 if y equals 0?
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
